All wonderful things come to an end, like that sad dream that running a machine 24/7 under your desk (at home) is cost effective.

Have you had those moments of Denial of Service because your 4 year-old was under the desk looking for his marble? saw some nice lighted diodes (i.e. machine is on) and decided to fiddle with switches seeing the lights go off and on, together with the straining fans as they go on and off?
